A coalition of eight conservative grassroots leaders wants Republican National Committee Chairman Reince Priebus to launch an internal investigation into questionable activities surrounding the June 24 runoff election for the Republican Senate nomination in Mississippi, which pitted incumbent Sen. Thad Cochran against state Sen. Chris McDaniel.

In a letter sent to Priebus Monday, the conservative signatories note an array of potentially illegal activities and express “outrage” over the campaign activities of RNC Member Henry Barbour, who directed the activities of a political action committee that was involved in the runoff and supported Cochran’s reelection. Among the actions the coalition wants investigated are racially incendiary campaign ads and literature, allegations of illegal vote buying, inciting illegal voting by Democrats in a Republican primary, campaign finance irregularities and violations of the RNC’s own rules.

These race-baiting robo-calls, race-baiting radio ads, race-baiting fliers, allegations of blatant violations of Mississippi election law, improper financial transactions, and old-fashioned ‘walking around money,’ all paid for by the Super PAC directed by Mississippi Republican National Committeeman Henry Barbour, amount to nothing less than the character assassination of Sen. McDaniel and his supporters. It cannot be tolerated,” said the coalition leaders in their letter to Priebus.

Along with an investigation of suspicious activities in the runoff, the coalition members want Priebus to speak out against the campaign tactics deployed in support of Cochran. “If you do not take the minimum steps necessary to investigate these dishonest activities, disavow this conduct and issue a formal censure or take other disciplinary action against those persons responsible, we will be left to conclude that you support the disregarding of RNC rules and the race-baiting smears directed at Sen. McDaniel and his supporters,” reads the letter to Priebus.

The coalition members include Jenny Beth Martin of Tea Party Patriots Citizens Fund; Brent Bozell of ForAmerica; former RNC Director of Grassroots Drew Ryun; Matt Kibbe of Freedom Works; Ken Blackwell of the American Civil Rights Union; Colin Hanna of Let Freedom Ring; Richard Viguerie of ConservativeHQ.com; and Tony Perkins of the FRC Action PAC.

The Republican establishment fear and hate the conservative movement personified by this group of signatories even more then the Democrats and are willing to lose Senate slots rather then allow the will of the people to prevail. The letter neglects to tell them what we will do if they fail to take action. Like lobby current legislative members to replace current leadership in the house and senate as well as the NRC.
